Protection Grading

Protection Grading is an important requirement in the electrical network to ensure discrimination and selectivity of downstream faults.

It is of vital importance that the protection system on any distribution network operates swiftly, correctly and that all the various relays grade to ensure that in the event of a fault the affected part of the network is isolated swiftly. The speedy operation of the protection system minimises the stress which the network is subjected to and limits the damage which can be caused to the network resulting from the flow of fault current.

Systems Power Engineering Limited offer a comprehensive range of protection service which include but are not limited to the following:-

  • Load flow and fault level studies
  • Protection system design
  • Relay specification
  • Grading studies
  • Intelligent electronic device selection
  • Setting schedules
